Does the reciever have digital inputs? If it does, then just get an optical digital cable and run it from your PS2 to your reciever.
Otherwise you could just hook up both the vcr and PS2 to your tv then hook the tv up to the reciever with the audio outputs on the tv, I am guessing you already have the tv hooked up to the reciever this way.
If you can\'t do it that way, then hook the PS2 and vcr up to the reciever, then hook a video cable up from the output on the reciever to the video input on your tv, you don\'t have to hook the audio up to the tv.
